NY Form RP-459: Accessibility Improvement Exemption

New York counties, cities, towns, villages and school districts may exempt the added assessed value of improvements that make a one-, two- or three-family home accessible for a physically disabled owner or household member (RPTL 459). Section 2 is the New York-licensed physician's certified statement of a permanent physical impairment. The owner files the application with the local assessor by the taxable status date.

Who completes it

The owner completes Section 1 (property, disabled resident, improvement, completion date and cost) and signs. A physician licensed in New York completes Section 2: license number and date of issue, patient details, whether a permanent impairment substantially limits a major life activity, a description, and how the improvement accommodates the patient.

Submitting and payment

How to submit it
The owner files the completed form with the local assessor (the Board of Assessors in Nassau County, the Division of Assessment in Tompkins County) on or before the taxable status date, which is March 1 in most towns.
Who pays
RP-459 lists no fee or billing code for the physician's Section 2 statement.

Good to know

  • The assessor can approve RP-459 only where the county, city, town, village or school district has adopted a local law or resolution, and each exemption applies only to that jurisdiction's taxes.
  • A legally blind person may attach a certificate from the State Commission for the Blind and Visually Handicapped instead of having a physician complete Section 2.
  • Taxable status dates vary: March 1 in most towns, January 2 in Nassau County towns, May 1 or June 1 in Westchester towns. New York City applications may be filed through March 15.
  • RP-459-c, the separate exemption for people with disabilities and limited incomes, relies on agency proof and has no physician section.

Frequently asked questions

Who can complete Section 2 of RP-459?

A physician licensed to practice in New York State. The physician enters their New York license number and date of issue, certifies whether the patient has a permanent physical impairment that substantially limits one or more major life activities such as walking, and explains how the improvement facilitates the patient's use and accessibility of the property.

What does the RP-459 exemption cover?

Only the increase in assessed value from improvements made to accommodate a physically disabled resident owner or household member. The assessor records the parcel's value with and without those improvements, and the difference is the exemption. It is available only where the local government has adopted it.

When is RP-459 due?

On or before the applicable taxable status date: March 1 in most towns, January 2 in Nassau County towns, May 1 or June 1 in Westchester County towns, and usually January 1 in villages that assess. New York City's taxable status date is January 5, but this application may be filed through March 15.
